TO ALL WHOM IT MAY CONCERN:

Beitknown that LRICHARD HARDENBROOK, of Bath, iu the county of Steuben, and State of New York, have invented certain new and useful Improvements in Grape-Ploughs; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specication, in which- Figure.- 1 is a plan or top view of agrape-plough constructed in accordance with and embracing my invention.

Figure 2 is a side elevation of the same, taken from the land-side.

Figure 3 is a plan view of the clevis, enlarged.

Figure 4 is a longitudinalvcrtical section of the forward end of the beam and the clevis, taken in line x 1:,fig. 1; and

Figure 5 is a section through the plough-beam extension or tail-piece and handles, takenin line y y, iig. 2.

Similar letters of reference denote corresponding parts in all the figures.

My invention relates to that class of ploughs more particularly designed for and adapted to the culture of grapes, in which the entire plough is contracted in width from the ordinary construction to enable it to pass readily-through between the vines without danger of catching or injuring the same, 4and is, in this instance,

made reversible to adapt it to pass back and forth between the same rows for the purpose ot' properly cultivating the same upon the adjacent sides.

The invention consists in a novel construction of the clevis, whereby the adjustment of the line o'f draught is made automatic when the plough is reversed, and whereby the depth of furrow is regulated by the adjustment of the clevis upon a single pivotal bolt, as hereinafter explained; and it further consists in providing the plough-beam with a flanged extension or tail-piece, to which the handles are secured by means of straps and through-bolts, as hereinafter explained.

To enable others te construct and use my improvement, I will describe,V the same with reference to the drawings, in which- 1 A represents the plough-beam, made of any usual or desired material, as wood or cast iron, and in `the form substantially as shown inthe drawing, figs. 1 and 2, and 'provided with the hanged extension or tail-piece Af, which forms a convenient means of attachment and support of the handles B B. The form ofthe tai1-piece or extension A', together with the arrangement of the handles relative thereto, is shown in cross-section, fig. 5, said handles being clamped and secured thereto by means of metal straps b, and through bolts e c, (see igs. 1 and 2.) C is the reversible mould-board, connected at its forward end` to a triangular block or point, C', which, at its rear or base, is provided with a socket to receive and allw it to turn upon a pivot formed on an arm or brace, D, extending from the plough-beam or upon the forward end of a shoe-piece or runner secured thereto, and E is a rear brace connected to the mould-board, and, by a pivot or joint simil-ar to that above described, to the rear end of the shoe or runner, or to a rear brace extending from the plough-beam or taihpiece, as shown in g: 2 ofthe drawing. F is an adjustable slotted arm, connected by means of a bolt, f, tothe beam A at or near its forward end, and having the groundwheel or roller G mounted on itslower end for the purpose of regulating and controlling the depth of furrow, and rendering the plough of easy draught. His the clevis, made or cast in one piece in'the form shown in detached plan view, iig. 3, that is to say, expanded in width at its forward end, and provided with the elongated and slightly curved slot 7L, and with the arms or fork L JL', which are perforated at their rear ends, as shown in ig. 2, to receive the bolt'ralby means of which the Clavis is attached to the beam A. Said clevis is further provided in its fork or at t'hcI junction of the arms with the expanded slotted portion of the clevis, with a'V-shaped lip, c, adapted to t in any one of a series of notches, d, of a corresponding shape, formed in the forward end of the plough-beam,` or of a metal plate secured thereto, in such manner as to allow the vertical adjustment of the clcvis bythe loosing or withdrawal and replacing of the bolt a, by which it is secured to the beam, and about which itis adjusted as a centre, thereby changing the line of draught, and., in connection with the adjustable ground-wheel H, regulating the depth of furrow at will. By making the slet in the elevis in the curved form shown, a forward inclination is given to the draught or bearingface, on whichv thel draught or coupling-ring rests, from a point central in the width of the clevis and slot to the ends thereof, in such manner that should the link or coupling be displaced or removed from the proper end by' a sudden jar or a temporary deflection of the line ci' draught, it willA be caused' immediately to return automatically to its place by such inclination of the retaining face ofthe elevis. This is'not the ease with any form of clevis new in use with which I am acquainted. I is a loopcor link of s form, one arm or hook of which .passes through the elongated slot in the clevis, and is free to slide from end to end' thereof upon the elevis, as the plough is reversed, or it is desired to change the line of draught. To the other arm of said hook the Whitfietree is connected by the usual ring or link. Said arni is provided with a pendent ring or lip, arranged as shown, g. 2, and which serves te allow the ready attachment of the whiiile-tree, but prevents 4its accidental withdrawal by dropping down behind the ring or other devicethr'ough which the connection is formed. K is a. hook or link, of any suitable construction, connected to the plough-beam and to the rear end lof the reversible mouldboard in such manne;` as to permit the said mould-board to be readily reversed, and to properly hold the same in either position, as shown in g. 1.

The operation of the several parts will be readily understood without further description.

Having new described my invention, what I claim as new, and desire to secure by Letters Iatent, is-

The clevis H, provided with the elongated slot t, perforated arms or fork z la', und lip e, when connected to the notched beam A 'by means of thc single pivotal bolt, substantially as and for the purpose described.

I also claim the curved form ofthe slot It, or the equivalent thereof, whereby n ,forwnrd inclination is given to the draught-bearing surface of the elevis vfrom the centre to the ends thereof, substantially as described.

I also claim the flanged extension or tail-piece A, formed on the beam A, as a means oi' attachment of'the handles B B, as described.

In testimony whereof I have hereunto subscribed by name this 6th day of July,1867.
